1.5 Configuration CPU 72x
On the CPU 72x are two DIP switches (S1 and S2) allowing the adjustment of the following
points:
Node address of the module
CAN bus bit rate of the module (CAN 1 on CPU 723-T)
Operation modes of the CPU
Type of the RS-232 interface
Bit rate of the RS-232 interface
The position of the DIP switches is only read at the start-up phase.
Switch bit 0…31 / bit 32…63
Settings see chapter "Installation, Startup, and Operation",
6.1 CAN Bus Configuration.
Special function with CPU 723-T:
0 = DIP switch S1 valid for CAN1
1 = DIP switch S1 valid for CAN2
The other CAN interface is set using the
SW functions of the library
SYSTEM_MLib can_hw_node_adr_n
and can_hw_bitrate_n in the application
program. The default settings are:
Bit rate: 100
kbit/s
Address: 0
